Although investing in a new heating or air conditioning unit may seem like a costly upgrade, replacing your home's heating and cooling systems has many long term benefits.  By updating your home's units, you will be taking advantage of advanced technology, ridding yourself of continuing maintenance fees and costly monthly bills and ensuring the health of your family.  Running outdated and inefficient systems comes with many problems, including frequent maintenance, high energy consumption and safety concerns.  Investing in a new system will require less upkeep, energy efficient appliances and updated safety standards.  You may also be eligible for tax credits and incentives from the provincial government.
